You were right in protecting the business. Nothing you say or do will help your ex until he decides to save himself. We have to protect ourselves and children.
I too am watching a girl at work do the same thing to her husband. "She is not happy". 20 year marriage, there is another much younger man. I tell her that it is important to keep committments and god hates divorce. Nothing really registers though. She keeps self-destructing. It is like the path to hell.
